How to: Get CPU temp

stephenw10

Here is the coretemp.ko file from FreeBSD 8.1 release (386).
Remove the .png extension. The file should be 8054 bytes.

Greatly sorry, changed to zip, now is OK ( http://ptt.4mg.com/pfSense/ )

You have:

coretemp32.zip–> inside amdtemp.ko & coretemp.ko ( FreeBSD-8.1-RELEASE-i386 )

coretemp64.zip--> inside amdtemp.ko & coretemp.ko ( FreeBSD-8.1-RELEASE-amd64 )

Hello ptt!
Many thanks!
As per other post it now works for me!

OK, as attached shows dashboard now shows my CPU temp. ;D ;)
Thanks to everyone here!

Hi Guys,
I'm still trying to make the coretemp module working but it seems I'm doing something wrong because it still doesn't work :'(.
I extracted the coretemp.ko from the FreeBSD 8.1 distribution iso and put it to /boot/kernel through a SCP connection authenticated as root.
run the kldload command and tried the command sysctl -a | grep temperature but it returns nothing.

I had no error when typing "kldload coretemp" so it should works !!!

My pfsense box is a Watchguard Firebox X700 hardware which runs on Intel Celeron 1200MHz.
This CPU should be supported by coretemp no ?

Please Help me.

Thanks in advance for your support.

Try with the core temp file Steve posted here - I used that one and it worked.

If you are using SCP to transfer the file.. ensure that you transfer the file in binary format. I had similar issue with WinSCP.

The coretemp driver only supports Intel Core cpus and newer. ;)

You have to use mbmon for older hardware such as the X700, which is Pentium 3 age.

Awesome …

I have to try this on my own box

thanks

With the file from Steve I had no issue even when using WinSCP…

Anyone had success to get all 4 temperatures to be shown in the dashboard?
That would really be neat.
Also, will an snapshot update break everything?

Steen

A snapshot would require you to re-edit the function file, other than that it will be fine.

Displaying multiple cores will take a little work. I've only programmed in Java before and I haven't really had time to sit down and take a look as far as exactly what needs to be added functionality wise. Right now, the function file returns true/false as far as if you can get temp and the cpu temp itself. It would need to return the number of cores and the temperatures of each core.

Yep, just did the latest snapshot update, so back to the editing board :)
Cheers Steen
Update:
After the snapshot update I had to recopy the coretemp.ko file to /boot/kernel/, then edit the system_information_widget.php file and edit the functions.inc.php file then I was back to "normal".

Thanks for the info Steve !!!

Now I have installed the mbmon package and I'm able to get system informations like FAN RPM, CPU and chipset temp from shell.
I've modified the Get_Temp function code in the system_information.widget.php as follow :


function get_temp() {
$temp_out = "";
exec("mbmon -c1 | /usr/bin/awk '{ print $2 }' | /usr/bin/cut -d ',' -f 1", $dfout);
$temp_out = trim($dfout[0]);

return $temp_out;

```}

This works fine in the shell.

I created the file /boot/loader.conf.local with "coretemp_load="yes"" inside (even if I'm not really sure that in my case it will be useful).

At this time, the "system information" widget in the dashboard of pfsense doesn't show the cpu temp.
Is there anything else to do when using mbmon instead of coretemp to make temperature info working ?

Thanks for your support.

Micro.

stephenw10

I phrased that badly.
I've only ever used mbmon from the command line.
It would be nice to have it work with the GUI though.

Steve

Micro

Oups,
I mean I modified the code in the function.inc.php file, not in system_information.widget.php

I'm not a programmer but a couple of months ago we had a topic about about supermicro boards with ipmi builts.. http://forum.pfsense.org/index.php/topic,34056.30.html Anyways, I copied the diag_system_activity.php page and change some of the code to display ipmi-sensors. I just did the same with coretemp. Its not on the dashboard but you can access it via the web interface.

Remove the .txt and upload it to /usr/local/www and you can access it via http://pfsense/diag_coretemp.php

To add it to the Diagnostics tab, add this to your config.xml:


 <installedpackages>[...]

<menu>
			<name>Core Temps</name>
			<tooltiptext>Core Temperatures</tooltiptext>
			Diagnostics
			<url>/diag_coretemp.php</url>
		</menu>

		[...]</installedpackages>

@Micro:


function get_temp() {
$temp_out = "";
exec("mbmon -c1 | /usr/bin/awk '{ print $2 }' | /usr/bin/cut -d ',' -f 1", $dfout);
$temp_out = trim($dfout[0]);
	
return $temp_out;

```}

This works fine in the shell.

This doesn't work for me. You can get mbmon to output the data directly like so:


[2.0-RC3][root@pfsense.fire.box]/root(26): mbmon -I -c1 -T 1
35.0

Steve

Edit: Yep this is working well for me. Here are the vchanges I've made to /use/local/www/includes/functions.inc.php

function has_temp() {

/* no known temp monitors available at present */

/* should only reach here if there is no hardware monitor */
return true;
}

function get_hwtype() {

return;
}

function get_temp() {
$temp_out = "";
exec("/usr/local/bin/mbmon -I -c1 -T3", $dfout);
$temp_out = trim($dfout[0]);

return $temp_out;
}

Highlighted red parts are changed. Don't forget to change false to true! ;)
